We have our Distribution Center and the headquarters communicated by two options: By a DS0 via Frame-Relay and with a pair of antennas. How could we connected both at the same time in order to obtain redundancy? What schema of switches we need? We had already 1 Cisco Catalyst Express 500 and a Cisco router 2801 in the DC. When DS0 "fell down", we connect directly to Cisco Sw the antennas and change configuration in Headquarters switches and routers adding 2 Vlans for that.
We'll appreciate every tip you can share with us.
Thnx a lot
